GEAR FOR MERRY-GO-ROUNDS.

which the following is a full, clear, and exact description.

The invention relates to merry-go-rounds in which crank-shafts areemployed foriniparting an up-and-down movement to the horses or htherseats.

The object of the invention is to provide a new and improved gear formerry-go-rounds arranged to accommodate any desired number ofcrank-shafts and to drive the same directly and at the same speed fromthe mainv gear-wheel, thus obviating all compounding of the gear andrendering the merry-go-round simpler and more durable in constructionand more effective in operation.

The invention consists of novel features and parts and'combinations ofthe same, as will be more fully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention is represented in theaccompanying (.lrawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a sectional side elevation of the improvement. Fig. '2 is anenlarged plan view of part of the same. Fig. 3 is a cross section of thesame on the line 3 3 of Fig. 2. Fig. 4 is'a section on the line 4 4 ofFig. 5. Fig. 5 is an end view of the head of one of the seat-supports inposition on the crank-arm of the crank-sl'iaft, the crank-shaft beingshown in section; and Fig. 6 is a section on the line 6 6 of Fig. 2.

On the central post A of the merr -goround is mounted. to turn a frameB, provided with the usual pin or lantern wheel C, in which meshes apinion D, secured on the ve'rtically-disposed shaft. E, connected withand driven by an engine or'other motor for rotating the frame B in theusual manner. On the frame B are ar anged radially-disposed crank-shaitsF, having at or near their outer ends the usual cranks F, on which arehung supports G for the horses or etherseats H. On the inner ends of thecrank-shafts F are secured bevel-pinions I in mesh with a large bevelgear-wheel J, secured at its hub to the central post A, so that when theframe B Specification of Letters Patent. Application filed April ll),

l is turned the crank-shafts Fare carried bodily lalong and are rotatedby their pinions I ines-hii'ig with the fixed gear-wheel'J. The rotarymotion of the crank-shafts F causes seats H.

In order to permit of driving each crankshaft F directly from the fixedbevel gear wheel -J without the use of intermediate cumbersome gearing,it is necessary to make the face of the fixed bevel gear-wheel Jsutliciently wide to accommodate adjacentpinions 1, the latter beingarranged in staggered form and overlap )ing each other more or less,according to t e number of crank-shafts F employed.

.It is understood that for large-sized merry; go-rounds a large numberof radial crankarnis F are necessary, and in order to drive all thesecrank-shafts directly from the gearwheel J by the pinion I it isnecessary to overlap adjacent pinions considerably more than is requiredfor sr-ialler-sized merry-gorounds having a less number 'ofcranleslialts F. The inneri'nost pinions l are less in diameter than theoutermost pinions to insure a proper meshing of the pinions with thefixed gear-wheel J and to maintain a uniform speed of all thecrank-shafts F. Thus bv largest pitch diameter of an innermostpinion Iis less than the smallest pitch diameter of the adjacent outermostpinion I but the same ratio of speed between the :tixed gear-, wheel Jand the pinions I is maintained.

Any one of the crank-shafts F can be thrown out of action, and for thispurpose the inner end of each crank-shaft is mount-ed to turn in aneccentric bushing K, journaled in a suitable bearing B, secured to theframe B, and on the said bushing K is secured an arm or handle K,adapted to be taken hold of by the operator to swing the same from anormal position over to a diametrically op 0- site position, so as tocause the bushing I to turn in its bearing B, and consequently lift theinner end of the crank-shaft F to move the corresponding pinion I out ofmesh with the large gear-wheel J. i

On the crank-shaft F, adjacentto the bearing B, is secured a toothedwheel L, adapted to move in engagement with a locking-piir L, secured toor forming part of the bearing B. Normally the toothed wheel L is out ofengagement with the locking-pin L-that is, at the time the pinion I isin mesh with the an up-and-donn or rocking movement of the" reference toFig. 32 it willbe seen that tlie gear-wheel J but when the shaft F israised by the action of the bushing K, as above explained, then thetoothed gear-wheel L moves. 1n engagement with the locking-pin L, andconsequently the crank-shaft F is locked against turning at the tinteits pinion I is out of mesh with the gear-wheel J.

Bf? thearrangentent described the crankshaft F can be rendered inactivewhenever it is desired to do so, sot-hat the seats carried by thecrank-shaft do not move up and down, but travel around with the frameB.v

If desired, every other crank-shaft may be thrown out of action, so thatan up-anddown moving seat is followed bf a stationary seat and thelatterfollowed b an up-anddown moving seat, and so on throughout theseries. I v

In orderto permit a convenient connecting and disconnecting of thesupports G withor from their crank-arni's F, the following device isprovided, special reference being had to Figs. 4 and 5: The head G of asupport G is in the shape of' a fork, provided at its 2 forked memberswith inwardly-extending lugsG adapted to engage recesses N,f01"l27l inthe top of a box N, through which extends the crank arrn'F of acrank-shaft F. The box N is preferably made in two parts, hingedtogether at one endand having their opposite ends fastened together by abolt, screw, ,or like means, as plainl indicated in Fig. 5. A button 0is fulcrumed on top of the box N andisadapted to swing with its freeends -over the lugs G so as to hold the same against accidentaldisplace-latent in the recesses N of the box N. f

On the crank-shaft F, *ithin the box N, is secured or formed a collar Ffitting a correspondinglp shaped recess in the upper part of the box N,so as to hold the latter from sliding on the crank-arm F in thedirection of the length of the crankeshaft F. The lower portion of-t-hebox N is made hollow to form a well for the lubricant, which by theconstruction described is not liable to work 'ou of the box and dropdown on the occupant of a seat. ."Whenever it is desired to disengage asun- 5 p0 Gi'rom its corresponding crank-arm F, th it is only necessaryfor the operator to s iviilg the button 0 out of engagement with thelugs G and then the o1: crater, by lifting the support G a shortdistance, causes the disengagement of the lugs G from the recesses N,and then the support G can be dropped downward to disengage the head Gcompletely from the crank-shaft F, as the distance between the innerends of the lugs G is somewhatmore than the diameter of.the ank-shaft F.If it is desired to disconnect 2e box X from the crank-arm F, it. isonly. pneces'sary to open -removal of the crank-arm.

From the foregoing it will'be seen that each the box for the convenienttn scenes crank-shaft F is directly driven from the up and down, itbeing understood that such inactive crankshaft is locked against turnmgmovement by the device above described,

. and shown in the drawings.

It is understood that instead of having a single fixed gear-wheel J of aWideface to accommodate two adjacent pinions I at the outer and innerface portions the main gearwhe'el J may be arranged in two or moreconcentric sect-ions; but in either case the same speed of thecrank-shafts F is maintained.
